Looking to buy a Primary Arms optic, and the Micro dots have interested me.

They have two listed on their site, the Gen 2 and Gen 3.

Gen 2:
http://www.primaryarms.com/product.sc?productId=303&categoryId=64

Gen 3:
http://www.primaryarms.com/product.sc?productId=304&categoryId=64


1) What exactly is the difference between the Gen 1 and 2? I only see "Kill Flash" listed under Gen 3. What exactly is Kill Flash?

2) Does the $60 and $80 include the mount needed for an AR-15? I am running an F marked A2 front sight.

3) And can anyone comment on the extra mounting instructions needed for these blems? Is it an easy fix, or is it something I would need to spend money on to fix?

4) Finally, I know this is a Micro Aimpoint on an AK, but are these PA optics the same size?

These are questions better directed at PA than CGN.

Contact their CS, it is superb.

I bought one, for my 12g, haven't gotten a chance to test it yet, but if you're going to use it on an AR you're going to need the riser. It sits very low.

Here's the Gen 2 on my AR. Yes, get the riser for $29. It should 1/3 lower cowitness. I haven't added iron sights to mine yet but will eventually. For $88 total, it's a great little package. The Kill Flash is an anti-reflection device designed to eliminate potentially compromising reflections from the objective lens. Not needed unless you plan on being in a combat situation. I plan on taking it to the range soon to zero it and to test it out.

All right, thanks for the replies. Will have to get it, but I will wait and see if the M3 clone comes in stock soon. Was $8 cheaper.

1) What exactly is the difference between the Gen 1 and 2? I only see "Kill Flash" listed under Gen 3. What exactly is Kill Flash?

Gen one was a completely different layout, more similar to the Sig Sauer or Konus Red dot. Gen 2 is the current model without a flash hider and gen 3 includes the flash hider. This is a killflash:

2) Does the $60 and $80 include the mount needed for an AR-15? I am running an F marked A2 front sight.

No, you will need to spend an additional $29 on the high mount to cowitness your sights with the dot.

3) And can anyone comment on the extra mounting instructions needed for these blems? Is it an easy fix, or is it something I would need to spend money on to fix?

I bought my Microdot before the issue was discovered. I mounted the dot to the mount as directed in the manual and haven't had any issues. Given. my use is limited to range plinking, but I am happy with it, especially after the $30 refund.

4) Finally, I know this is a Micro Aimpoint on an AK, but are these PA optics the same size?

Yes

I'm thinking of putting one of these on my .22lr AR to mimick my h-1 setup on my .223

You might want to check on the size of the red dot and compare that to the average distance you plan on shooting before buying. If it is 4 or 5 moa, that might be a little large for 100 yards if you are trying to get small groups. But to each his own, some people might like the larger dots. I myself prefer a 1 or 2 moa dot for 100 yards.

I will be shooting at 100 yards.

Is this optic not good for close range shooting?

Will just be limited to range use.

I use a Gen3 PA Micro on my Benelli SuperNova..no riser- mounted right on the rails- holding steady with the 4MOA dot.

I tried a Gen2 on a 22 AR Upper- the 4MOA dot was perfectly fine out to 25 yards.

I regularly use a Multi. Rect. M3 w/ high cant mount on my dedicated 22 upper. If you're concerned about smaller size MOA dots this is the only one with a 2MOA dot.

Love em all, can't say enough good things about them!

That's nice to know! I just ordered one to test out on my 870; happy to hear they are up to the task!

The PA reddot is slightly longer overall than an aimpoint micro. Learned this when I tried to use my aimpoint micro scopecoat on my PA -see my for sale thread for an unusued micro scopecoat...:rolleyes:

So what exactly is the problem with mounting these things?

Davidoff

There is no issue with mounting the Microdot. The issue is that the chinese factory that made the Microdots drilled the holes for the mounting screws through the scope body. The Microdot comes with a low mount installed with loctite on the screws. When removing the low mount to put on the high mount, the inside of the scope is exposed to water vapor, which could lead to the glass fogging up when going from a warm moist enviroment to a cool dry one. I'm not planning to use my Microdot in those conditions so I consider it a non-issue. If I had wanted a bulletproof dot I would have bought an Aimpoint, I just wanted a dot of good quality that would hold zero and not break. I'm happy with my Microdot, and I would reccomend it to anyone for a range/fun rifle.

Here's some pics:

Thanks for the info Davidoff.

How hard is it to remove the standard mount with the loctite?

not hard at all, the riser comes with the right size allen wrench in the box.

Yup, its a little stiff, but it will come right out. (That's what she said)

Thanks for the info. Will place the order tomorrow hopefully.

Also, is that a mid length with an A1 stock? If so, I run the same set up minus the grip... will change that out soon though.

Yup, middy with A1 stock. I like the solid feel and better cheekweld of the standard stock, but the A2 is a little long. I had a friend's A2 on it for a couple weeks to try it out, and I ended up selling my VLTOR and putting the A1 on.

Going a bit off topic for a second...

I agree, I like the solid feel. The cav arms A1 stock is great. Noticeably lighter than my A2 I just removed, and shoulders much better.
